Which action must be taken to confirm a new base branch when modifying a user story?

To confirm a new base branch when modifying a user story, it is essential to click on Apply. This action indicates that you are finalizing the selection of the new base branch for that user story. By clicking Apply, the changes you made regarding the base branch are saved and acknowledged in the system, ensuring that the user story is now linked or associated with the newly designated base branch.

Understanding the context of this process is crucial, as it involves managing branches in a version control system. Selecting a base branch is a critical step that determines where the changes from the user story will be integrated. Without applying the changes, the selection of the new base branch will not take effect, potentially leading to confusion or the continuation of work based on the old base branch.

In addition, when working with user story modifications, pressing Commit Changes or Finalize Changes refers to committing modifications or finalizing them in a more general sense, but does not specifically address confirming a base branch. Selecting Base Branch sets the desired branch but lacks the step of confirming that change by applying it. Applying changes is the definitive action to take for this specific scenario.
